"Elementary lathe practice : As adapted to the teaching of machine shop…" by T. J. Palmateer is a technical instruction manual written in the early 20th century. Aimed at beginners in technical schools, it teaches foundational engine‑lathe operations and shop practices, focusing on accurate turning, facing, tapering, threading, boring, drilling, reaming, and knurling through tightly designed practical exercises. The book is organized around three progressive exercises. The first covers cutting stock, centering, mounting between centers with a dog, facing, rough and finish turning, tool setting and grinding, speed choices, tailstock adjustment, gauging, and filing to produce a close running fit of a shaft to a collar. The second adds layout to length, recessing, taper turning by offsetting the tailstock, and a comprehensive approach to thread cutting: 60-degree tool geometry and gauging, gearing the lathe for pitch, engaging the split nut, using stops, reversing, and finishing each flank (or using a compound rest), with checks against standard nuts. The third shifts to cast iron and workholding: truing a rough casting in a four‑jaw chuck, rough boring with a flat drill and boring bar, reaming with shell and rose reamers, cutting inside threads, scraping finishes, and setting and machining a 30‑degree seating. A mating piece is drilled, reamed, mounted on a mandrel for external finishing, threaded without relief, its taper fitted and blued, and its boss knurled. Throughout, the instructions emphasize accurate measurement, proper lubricants, controlled feeds and speeds, and safe, efficient setups to produce true, smooth-running parts.
